增温对我国森林生态系统影响的研究进展OA

Climate change is a major global challenge with profound impacts on the structure and function of forest ecosystems.As a vital carbon sink in the terrestrial ecosystem,forests play a crucial role in climate regulation and biodiversity maintenance.However,global warming is rapidly altering the structure and function of forest ecosys-tems.To clarify the effects of warming on forest ecosystems and underlying mechanisms,we systematically reviewed research progress both in China and abroad.Based on the findings from simulated warming experiments and ecologi-cal modeling studies conducted in China,we explored the effects of warming on nutrient cycling(carbon,nitrogen,phosphorus),hydrological cycle,plant phenology(both above-and belowground),plant physiological traits(roots,stems,and leaves),and the structure of soil microbial communities.Warming influenced material cycles and energy flows by affecting the structure and function of soil microbial communities and plant physiological and phenological characteristics,ultimately impacting nutrient supply,carbon sink function,and biodiversity mainte-nance ability of forest ecosystems.Although there have been significant progresses,it is necessary to further in-tegrate multidisciplinary technologies to conduct long-term and cross-scale studies on the synergistic effects of multi-ple factors,which would provide theoretical support for the sustainable development of forests.
